CORD-HOLDER FOR GRAIN-BINDERS.

SPECIFICATION forming part of Letters'Patent No. 430,697, dated June 24, 1890.

Application filed July 13, 1888. sennno. 279,816. (No model.)

My invention relates to that class of cordholders in which a notched rotating-Wheel is employed in connection with a yielding shoe or clamp for holding the ends of the band received from the needle, and more particularly a to the construction of the holder whereby the clamping-surface is shortened to allow the cut ends of the band to be released and drawn out of the holder in the act of discharging the bundle and of cutting the band at the needle end thereof, thereby preventing an accumulation of short cut ends in and the consequent clogging of the holder, as hereinafter described and claimed.

In the accompanying drawings, Figure 1 shows in rear elevation my improved cordholder and other parts of the binder mechanism in connection with which it operates. Fig. 2 is a side view, partly in section of the parts shown in Fig. 1, looking from the stubble side. Fig. 3 is a side elevation of the cord-holder, wheel, and shoe, showing also the pinion for rotating and the delay-cam for I holding the wheel in the intervals of its movement. Fig. 4tis a perspective view, and Fig. 5 a plan view, of the shoe detached; and Fig. 6 is a face view of the notched wheel or rim, showing the pinion and delay-cam.

A indicates the knotter-actuating shaft; A, the knotter-actuating cam and gear wheel fast on said shaft; B, the knotter stand or frame suspended from the shaft A and supporting the knotter breast-plate O, the latter being attached to flanges or feet on the lower end of said stand 13, and D is a pivoted frame or sleeve, in which the knotter-shaft E is journaled, said frame D being connected by a pivot d to the frame or stand B at a point above the shaft A to permit the knotter E on the lower end of shaft E to be vibrated toward and away from the plane of the cam- Wheel A. The frame or sleeveD is provided with arms or bosses e e one of which has the knife F secured to it to vibrate with the frame D, and the other a spring-plate F,

which acts in the revolution of the knotter to close the movable jaw upon the fixed one for clamping the ends of the band.

. G indicates the needle.

The above-named parts are described and.

holder; but any usual construction and arjrangement of said parts may be employed.

Upon the knott-er shield or breast-plate O,

or other suitable support, is formed or otherwise secured a lug or short upright H, sup- -the cord-holder wheel I is journaled.

porting an inclined stud-shaft h, on which This A, and holding the wheel I and its pinion stationary in the intervals between their intermittent rotating movements.

The wheel or rim I is shown provided in its outer face or end with cord-notches i t" 4?, and the delay-cam plate or disk J is shown provided with segmental depressions, forming delaysurfaces corresponding in number to the number of cord-notches in the wheel I. The

- outer end of the wheel or rim I has a peripheral flange or rib 1 formed upon it, which is cut away at the cord-notches, and which enters and carries the portion of band material received, from the needle into the shoe indicated t K, and also serves to hold the shoe on theicord-wheel. The shoe or cord clamp K is made concave on its upper face to conform to the diameter of the wheel or rim I,

and is grooved at Ya to receive the rib I, and itsclamping-face 7c is made of a length just sufficient to extend from one to another of the notches in the cord-holder wheel or rim Ithat is to say, supposing the cord to enter the notch d in said wheel, it is carried by the V partial rotation of the wheel and by the action of the portion of the rib I in rear of said notch into the shoe, where it is clamped between the outer face or periphery of the rim or crown-wheel and shoe, and is moved inward toward the knotter (in the direction indicated by the arrow) for yielding cord thereto until it reaches the end k of the clamping-face of the shoe, when the movement of the wheel ceases just as the knotter has completed its revolution for forming the knot and is ready to be vibrated for causing the knife to cut the band material and for drawing itself out of, and the end of the hand through, the loop. In this movement of the cord-wheel the portion or end of the band extending from the needle is left held between the clamp and wheel extending from the notch 'Z to the notch t" of the latter. At the next movement or partial rotation of the wheel I the portion or end of the cord held, as above described, is

and is freed just as the knife is vibrated to cut the cord, and, instead of being cut with i the portion at that time connecting with the needle, is drawn out of the cord-holder, attached to, and is discharged, with the bundle, instead of being cut off and left in the cordholder, as it has been in constructions heretofore in use. v

By the construction described all clogging of the holder by cut ends of the band mate rial is avoided, and the resistance to the action of the knife is reduced, as the knife is required to cut but one cord instead of two. The knife employed is hook-shaped, and has its cutting-edge on the inner face of its hooked end, so as to cut the band as it, is vibrated outward or away from the cam and gear-wheel A with the knotter, as the latter, after having formed the knot, is vibrated for withdrawing it from the loop and for drawing the ends of the band through said loop.

The shoe or clamp is provided at its inner receiving end with a fork or two projecting curved prongs Z and Z, the first named serving as a guard to cover the notch in the cordwheel at that point and prevent the cord from the needle from entering and being caught'therein, and the other Z, which di verges from the prong Z, serving in connection with the latter to guide the cord to the outer receiving-notch. The shoe has at its outer end an outwardly-projecting sp-urm,

inclined on its upper face, upon which the holder having a series of notches to receive 1 the cord, a cord clamp or shoe having a clamping-surface bearing against the face of said cord is laid by the needle, and which serves to deflect said cord and carry it into the notchin the wheel. Said outer end of the shoe is also provided with a curved prong or hook m, which extends around the notchin the wheel, its upper end resting in contact or in close proximity with the rib 1 above said notch for preventing the cord from the needle from wrapping around the wheel and insuring its escape through the succeeding notch.

The clamp or shoe K is provided on its lower face with a spur kiwhich enters a perforation in the outer free end of a fiat spring L, attached to a suitable support on the breast-plate, and which serves to uphold the shoe in yielding contact with the cord-holder wheel.

In another application filed April 21, 1888,

Serial No. 271,381, I have shown a construction of cord-holder resembling that herein shown and described, but differing from it in that the clamping-surface of the cord clamp or shoe is not therein restricted to a single clamping-face only, (said face extending only from center to center of or between two adjacent cord-notches of the crown-disk,) nor to r a specific arrangement of the guard or "cord 5 guide on the inner end of said clamp, which Ition herein claimed. a carried to the discharge end 10 of the shoe constitute the salient features of the inven- 1. The combination, in a grain-binder, of a knotter, a rotary cord-holder wheel or disk having a series of cord-notches, and having 1 an intermittent movement imparted toit during each revolution of the knotter, a knife operating between the knotter and said wheel to cut the cord, and a clamp or shoe arranged to engage the cord on the side of the wheel i away from the knotter, the side of the wheel past the end of the clamping-surface of said shoe and release it in advance of the action of the knife to cut the cord, substantially as described.

2. The combination,with acrown-disk cordholder having a series of cord-notches, of a 1 clamp or shoe having a clamping-surface bear-.

.ing against the disk between two of said jnotches only, and a guard for preventing the gcord from entering the notch in the disk at ithe end of the shoe nearest the knife while ithe needle lays the cord in the notch at the j opposite end of the shoe, whereby the end of the cord extending around the bundle is re ;leased in advance of the action of the knife i on the cord, substantially as described.

3. The combination of a crown-disk cord-- disk between two of said notches only, said disk and shoe being provided one with a 1 groove and the other with a retaining-flange, and a guard at the inner end of said shoe for 7 preventing the cord from entering the notch nearest the knotter while the needle lays the.

cord in the open notch in the opposite side of said disk, substantially as described.

4. The combination of the crown-disk cordholder having a series of notches, the clamp or shoe E, having a clamping-surface extending only between two of said notches, the guard e at the inner end of said shoe for preventing the cord from entering the notch nearest the knotter While the needle lays the cord in the open notch in the opposite side of O.
